Webview Page not available when tried

We have IPCCE 7.5.1 with CVP, webview reports were working fine and were accesable from all the workstations in the network, but currently i am not able to access it and it gives me " The page cannot be displayed " when tried https://AW/instance , and when http://AW/instance , it gives me "HTTP Error 403.4 - Forbidden: SSL is required to view this resource.Internet Information Services (IIS)"

So i tried accessing it from the AW server and it worked just fine,

Its only working from the AW server, i have tried it from the Progger server and its not working from there as well.

Thank you very much for your response, but thats not the case, since i was using it and it was working but now after security hardening being applied on the AW server, i am not view it, the only place its working is the AW server it self, even i have tried it on the PG server and i am getting the same result.

I have seen your recommended solutions in this forum and i knew you will come up with something.
